Hi
When I am on a call initially if I remove the phone from my ear, the screen will wake up and show the call screen.
However after a few minutes on a call the screen won't wake up again. If you press the lock button, it locks, then a 2nd press it's locked and illuminated as normal.
Getting a pain on calls where you need to be able to press numbers (voicemail) or when wanting to end a call.
I have the May security update software version & S21 256gb
